6. 960 hours

7. 8000 biscuits

8. 7200 apples

9. 180 minutes

10. 366 days

Explanation:

5) 365×12 + 366×3(leap year)

=5478 days

6) in 1 day there are24 hours so in 40 days there are

40×24 hours

=960 hours

7) In 1 packet there are 20 biscuits so in 400 packets there are

400×20 biscuits

=8000 biscuits

8) In 1 tree there are 90 apples so in 80 trees there are

80×90 apples

=7200 apples

9) In 1 hour there is 60 minutes so in 3 hours there is

60×3 minutes

=180 minutes

10) In 7 months there are 31 days (7×31=217)

In 4 months there are 30 days (4×30=120)

In 1 month there is 28 + 1 to make leap year (1×28+1=29)

217 days + 120 days + 29 days

=366 days
